1 Claim. 1

This invention relates generally to electrically operated vibrating devices and is directed particularly to improvments in joggers for use in straightening or evening the edges of stacks of paper sheets.

In many onices, small printing shops, and other establishments, it is frequently necessary to straighten the sheets in a stack of papers and this is customarily done by lifting and dropping the sheets on edge, or jogging the same, on a desk top or other flat surface. Equipment is obtainable for doing this work mechanically but it is relatively expensive owing to the use of com.- plicated mechanism and accordingly small printing shops and other small business establishments are usually unable to afford such equipment and the work is accordingly done by hand.

It is a principal object of the present invention to provide a simple, efficient and economical jogger by means of which the straightening or evening of the edges of the paper sheets in a stack may be accomplished quickly and with a minimum of effort.

A further object of the present invention is to provide an improved paper Jogger which is constructed to function automatically upon the placing thereon of necessary Weight of paper, without requiring that the operator turn on or oi controlling switches for the electrical mechanism by means of which the jogger is actuated.

Another object of the invention is to provide an automatically operated paper jogger which is started or put into operation by placing a sufficient weight of papers thereon and which is automatically stopped upon the removal of the weight.

Still another object of the invention is to provide apparatus for accomplishing the above stated results with means whereby static electricity may be automatically removed from the paper sheets during the jogging operation so that the sheets will not stick or cling together and may accordingly be more -easily shifted and straightened.

A still further object of the invention is to provide in a paper jogger of the character stated, a means whereby the mechanism may be adjusted to respond to different weights of paper stacks so that after it has once been set for use in association with paper stacks of a predetermined size it will thereafter continue to function automatically each time a stack of such size is placed thereon and removed therefrom.

Other objects and advantages of the invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in association with the accompanying drawings, with the understanding, however, that various changes and modifications may be made in the invention within the scope of the appended claim.

In the drawings:

Figure l is a view in top plan of a paper logger constructed in accordance with a preferred embodiment of the present invention.

Figure 2 is a View in top plan of the device with the cover plate and jogging platform removed, showing the mechanism within the casing, the platform post being shown in section.

Figure 3 is a front to rear section taken in a vertical plane substantially on the line 3 3 of Figure 1,

Figure i is a vertical section taken substantially on the line 4-4 of Figure l.

Figure 5 is a vertical section taken substantially on the line 5-5 of Figure 1.

Figure 6 is a detailed section taken substantially on the line 6--6 of Figure 5 showing the adjusting means for the control switch.

Figure '7 is a detailed section taken substantially on the line 'I'I of Figure 1.

Figure 8 is a View in top plan of the jogger showing a modified or altered arrangement for the resilient supporting elements for the platform.

Figure 9 is a partial top plan view of the jogger showing another arrangement or modication of the resilient supports for the platform.

Figure 10 is a detailed section taken substantially on the line IIJ-Ill of Figure 9.

Figure 11 is a detailed view showing a modification of the switch setting and adjusting mechanism.

Referring now more particularly to the drawings the numeral III generally designates a casing or housing in which the operating mechanism for the jogger is encased. As shown this casing or housing comprises a bottom Wall II, side or end walls I2 and front and rear Walls I3.

Two of the Walls, here shown as the front and rear Walls I3, have portions of the top edges thereof turned outwardly to provide langes I and overlying the open top of the housing and resting upon the flanges I4 is a top wall or cover plate I5 which is removably secured to the flanges I4 by suitable securing elements iii here shown as nuts and bolts.

While the construction thus far described is preferred it is to be understood that the inven- 3 tion is not restricted to the specific arrangement and means for maintaining the top wall I5 in place as, obviously, other arrangements might be employed without departing from the spirit of the invention.

The top or cover plate I5 is preferably formed of some non-metallic material such as wood, pressed fibre board or the like, while the body of the housing may. be made of aluminum or any other suitable material, not necessarily metal: as it will be readily apparent that other materials such as plastics or the like may be employed.

Since the jogging device is light in weight and relatively small and therefore is adapted to; be;

moved about to be placed upon a desk top or counter, it is preferred that suitable pads or cushion feet II be secured to the under side off the bottom I I so as not to mar any surfaceupon which the device may be. placed.

The numeral I8 designates a top deck or platform which is of greaterwidthandl lengthI or depth than the top I5l of thehousing andi-which. is maintained over and in spaced relation with. the top I5Y in the manner as shown and-y about to be described. This plat-form I8 is preferably made of some materialv which isA nonconductive4 of electricity such as breboard, wood", plastic on the like and is supported adjacent its: four cor.- ners, upon the housing topl wall I5? by resilient elements I9r whichmaybe of any suitable character but are preferablyin the form ofr blocks of sponge rubber. Itj is to beunderstood, however,

that the use off a generic termin the claim to` deiine these resilient supports i's intendedV tov cover sponge rubber or rubber ofV any other character ofV any other suitableresilientsupporting members interposedl between the` platform and the top wall 15which will serve thedesired purpose.

In the embodiment of the invention` as` illus..

trated in Figure l it will be seen that the resilient bodies I9 are in the form of rectangular-blocks, each set at one cornerof theplatform and positioned to have its long sidesparallelingthefront and rear walls ofthe housing.

Another arrangement forY the resilientV bodies I9 is illustrated in Figure 'whereit will be seen that the bodies, here designated' I9, maybe disposed each across the corner adjacent toiwhich it is located while in Figures 9*A and 1.0; still another arrangement is shown wherein a resili ent supporting block of rectangular form, here designated I9, is disposed across each corner of the top wallv I5' and adjacent to-andlpositionedinwardly from each block I9' is: a secondl resilient block or body 20 which rests upon or isse.- cured to the top of the wall- I5` but 1s of. less height than the adjacent block I9." which joins: the platform and wall. By the provisionA or"` theA additional cushion or support 20, if abnormally heavy loads of paper are being jogged', a com,- pression or downward movement of the platform to an undesirable extentA is prevented.

Within the housing there is securedtothe.

4 and has the downwardly and inwardly extending' inner end portion a, the free end of which is disposed beneath the free end portion 23a of the upper switch arm.

The portions 23a and 25a of the switch arms, carrying the contact members 26 and 21 respectively which are arranged to have a normally spaced relation as shown in Figures 3 and 5, are only. brought into.. electrical., connection. one with the other uponV the. imposition of afload'upon the platform I8, as hereinafter described.

Means is provided whereby the spacing between the terminals 26 and 21 may be changed 11? adjusted as desired, such means being as folows:A A sleeve 28'has a threaded end portion 29 which 1s; extended through a suitable opening in the forward Wall I3 of the casing, directly beneath the switch blades 23 and 25 and this sleeve is secured rigidly in position by the clamping nuts 3li which. are threaded ontothesleeve at the lnnen andloutersides-of the wall. sothat the wall can be gripped? therebetween and thus1 the. sleeve- 281maintained rigidly in position within thecasing below the insulation body 2|.

Extending through` the sleeve 28- is ashaft 3l uponi the outer endl of which., is-securedthe-knobI 32- by means of which rotationy of theshaft may= beeffected.

Within. the casingthey innen end ofi the. shaft 311|V hasu secured thereon between the clamp. nuts 33: which are threaded onto theshaft, an ecoen' trim disc` or cam 341; of:` insulation material; the

periphery ofwhichcam bears against the under.-.

side of the str-aightportion off the switchl arm 2,5'l at a substantial? distance inwardly from the body 2.I=. Interposedfbetweenfa washer 35 surrounding: the shaft atz3 I= andibearing against the inner' end off the sleeve-2B', andi the adjacent clamp nut 332, is anz expansion spring 361' which normally urges the shaft 3.Ii inwardly-"so asto'lmaintain the eccentricdisc 341 at its inner-most position beneathL theA .straight portion of the switcharm. or-blade 25;

It willbeseen fromy the foregoing that by.; turning the/shaft 3I upwardzthrustzmayA be applied to the: switch. arm 2.5:' to' shift'. the` contact 21 with respect to` the contact` 26. therebyy alteringY the.

through and adjacent to= the endsofsailorlg fiat plate 4m of." insulation material; upon which` is.

mountedl andi securedgani alternating current. type., vibrator unit '.whichisagenerally designated-41|'.

The vibrator unit 31| comprises a, metall base. plate 42s which isboltedito; the insulation, plateAO; as indicated at d3 and formed integral with-:thc plate` 42 isthe; upstandna resilient substantially Qeshapedyoke 44, which; hasthe horizontally: diri-V posedZ upper; end, portion, 44a; which. carries, the, long, armaturebar 45, t he-,-portion 44a, of theiyke beingY joinedy to` the armature bar 45, at one side of theflatter. and. approximately midway between its. end, as is clearly'shown. in Fgurev2.

Disposed. upon. themetal base plate 42j` of the vibrator unit. is a, laminated, magnet frame 46 which. comprisesthe upstanding end; arms 41' and thecentral core, portion 48. Within this frame and encircling the core 48 is the magnet coil 49 with the two ends of which are connected the current conducting wires 50 and 5|.

rEhe vibrator unit and the insulation plate 40 rest upon the end portion 23a of the switch blade 23. This switch blade or arm 23 supports the unit and upstanding guide pins 38 function to prevent the unit from turning or rotating.

It will also be seen upon reference to Figure 4 in particular that the armature bar 45 lies above the ends of the frame arms 41 and the core 4B and are normally in spaced relation with the same.

Secured to the armature bar 45 centrally between its ends, is an end of an upstanding post 52. This post extends through the opening 53 in the top wall plate l5 and abuts the underside of the platform I8 through the medium of a suitable washer 54 although it may abut directly against the platform as will be readily apparent.

The upper end of this post 52 has a tapped bore therein into which is threaded the shank of a screw 55 which passes through the platform I8 and has its head exposed upon the top of the platform as shown in the several figures. This screw 55 which is of current conducting metal and in electrical connection with the metal post 52, has a double function. One function is, of course, to establish a rm coupling between the platform IS and the armature bar 45 through the medium of the post 52 and its second function is to serve as a means for carrying off static electricity from the paper sheets as they are being jogged and straightened on and by the machine platform.

The current conduction wire 50 forms one of the usual pair of wires of a current conducting two-wire cable 5t while the other wire of such cable, designated 51 is electrically connected as indicated at 58 with the switch arm 23, through the medium of one of the two securing screws 22. As illustrated in Figure 2 the cable 56 is extended through a suitable hushed opening at 59, in a side wall of the casing and connects with a plug 6l] of the usual two-prong type commonly employed for connecting a current conducting cable to a standard type of outlet fixture.

The current conductor 5l which is connected to the other end of the wire coil 49, is electrically connected as indicated at 6I with the lower switch arm 25 through the medium of one of the two screws 24 by which such arm is secured to the insulation body 2 l.

Figure ll illustrates another or modified arrangement of the spring arms forming a part of the switch structure. In this arrangement the arms are supported upon a block 2|a of insulation material, corresponding to the block 2| and the lower arm 62 of the switch assembly, is relatively short and has one end positioned upon the top of the block 2 la. The upper or longer arm as designated at G3, has one end disposed upon a block 554 of rubber or suitable insulation material, which block overlies the end of the arm 62 and the two arms together with the block of insulation 64 are secured to the supporting block 2 I by screws 65.

The free inner end of the upper long spring arm of the switch unit has the insulation plate te of the vibrator unit bearing thereupon as illustrated. The eccentric disc by means of which the spacing between the switch points or terminals 2B and 2'1, is altered, is designated 34 and the means for operating the same is of the same construction as that shown and described in connection with the structure illustrated in Figures 3 and 5.

In the operation of the jogger the Switch points 26-2'1 or 2G-2l, may be given a tentative setting by rotation of the control eccentric wheel 34 or 34', to have a slightly spaced relation and a quantity of paper sheets then placed on edge upon the top of the platform i8 to eiect compression or downward movement of the platform against the resilient support of the members IS. Since the vibrator unit is essentially suspended from the platform, this downward movement of the platform will also effect downward movement of the unit and if the quantity of paper is of suincient weight the vibrator will be moved downwardly until the switch points are brought together whereupon electrical energy will be caused to iow to the vibrator coil and a rapid vibration or up and down movement will be imparted to the platform I8 to effect the desired jogging of the paper sheets. If the quantity of sheets is insufficient to bring the contacts together more sheets may be added or the adjusting eccentric can be turned to force the contacts closer together, as may be desired and after the desired setting is obtained then the work may be continued without having to change the setting and without having to bother with the turning on or off of the electric current since this is accomplished automatically through the weight of the paper placed upon the platform.

As is well known paper sheets when shifted relative to one anotherl particularly as in the process of discharging the sheets from a printing press onto a stack where one sheet slides over the surface of another, static electricity is produced which tends to cause the sheets to cling or stick together so that their rearrangement may be somewhat difficult.

By the provision of the metal screw or contact 55 which projects above the top of the platform i8 and is electrically connected with the underlying metallic parts, such static electricity may be eliminated from the sheets by the operator using the device passing the paper load edge back and forth over the screw head or button while the sheets are being jogged, thereby causing a rippling or combing action through the paper. Thus, as previously pointed out, the screw by having its head raised above the top of the platform, performs the two functions of coupling the platform to the Vibrator and forming a means for draining or leaking off the static electricity from the paper sheets as they are being jogged.

Since the surface area of the platform is very large as compared to the surface of the screw head, there is ample room upon any side of the screw head or button for normal jogging as will be readily apparent.
